Origin & Breeding History: 'AAC Odyssey' (experimental designations AR2015-12, F10090 and 15789-14) originated from a cross made between the variety 'Huckleberry' and the experimental line F02041 conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2008. In 2009, the true potato seed resulting from the cross was sown in a greenhouse at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre and the resulting seedling tubers planted at the Benton Ridge Research Substation of Agriculture and Agri-Food Canada near Woodstock, New Brunswick, in 2010. A clone designated as 15789-14 was selected in 2010 from a single hill trial based on vine maturity, tuber appearance, shape, size and flesh colour.

Tests & Trials: The comparative trial for 'AAC Odyssey' was conducted during the 2019 growing season at Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick. The trial consisted of 2 replicates per variety arranged in a RCB design. Each replicate consisted of 40 plants in a 12 metre length row. The rows were spaced 90 centimetres apart and the plants were spaced 25 centimetres apart within the row.
